Drive Optimization with HMI Advanced
14
14.1 Overview
HMI Advanced offers comprehensive functions for analyzing controller action of drives
connected to a SINUMERIK 840Di sl:
● Frequency response measurements for current, speed and position control loop
● Automatic controller setting
● Funktionsgenerator
● Circularity test
● Servo trace
Measuring functions
The measuring functions make it possible to assess the automatic controller action of the
respective control loop (frequency response) by the integrated FFT analysis (Fast Fourier
Transformation) without external measuring equipment.
The measurement results are represented graphically as a Bode diagram. HMI Advanced file
functions can be used to archive the diagrams for documentation purposes and to simplify
remote diagnostics.
Circularity test
The circularity test serves to analyze the contour accuracy on the quadrant transitions of
circular contours achieved by means of friction compensation (conventional or neural
quadrant error compensation).

Servo trace
Servo trace provides a graphically assisted analysis of the time response of position
controller and drive data.
